This integrated circuit is a battery backup circuit featuring a 4.65V threshold voltage, active low reset, and watchdog timer. It monitors a single voltage with undervoltage detection at 4.5V and overvoltage detection at 4.75V, providing a power fail warning. The device offers backup battery switchover and a reset delay time of 280ms, with a reset timeout of 140ms. Operating with a supply voltage range of 1V to 5.5V and a maximum supply current of 100uA, it is housed in a leaded SOIC package suitable for surface mounting.
